Really nice example of street photography there! It's funny at first glance (especially given the title, which is an important additonal factor which can be overlooked - thinking of decent titles is a skill in itself), but then when your eye actually moves back to the guy on the left, it suddenly feels just a little intimidating!

From a technical point of view, there's not much to criticise - you arguably could have increased the contrast or added some very mild grain, which would both give a grittier look if you wanted to go for the "intimidating" look, but it certainly isn't necessary. Nice shot!

I really like this, very effective tones, an old and obvious idea but done extremely well. I also like the framing, but my only reserve would be the odd choice (if it was a choice) to have it slightly off-centre, that jangles a little and seems very out of place. Cropping a little tighter on the left-hand side of the picture would address that just a little?

The clothing and hair work really well, and I like the overall tonality of the image, plus the plain (but not cold) background really brings out the model's warm tones and colours, so good work on those angles.

I'd have to agree wholeheartedly on the expression she has though, as not only does she not look very comfortable or happy, she actually looks decidedly UNhappy to me!

So I guess the main suggestion I'd make here is about you being in a position (as the photographer) to take more control of such things - remember, even if the model is paying YOU to take the photos, you're still the only one who can see their face/pose/expression etc, and so the responsibilty is on you to suggest changes and alternatives. Unsurprisingly, although some people are naturals, and some people who tout themselves as pro models are actually useless, I tend to find that the less experienced models are sometimes nervous and inexperienced (as you'd expect) and can be too busy worrying about sucking-in their stomach or whatever else to remember to keep the expression and other elements of the pose looking natural and relaxed (if natural and relaxed is what's required).

So, don't be afraid to direct models as you want, and take as long as you need to get it right. Almost anyone (pro or otherwise) in front of the camera will appreciate rather than resent some gentle direction.

Overall, the image looks really nice, and it's a good choice of background. I also think the indirect positioning works well.

I'd say that if you're taking a picture of something that someone else made, then you do need to be representing it in a way that either heightens the artistic creativity of the person who made it, or includes some of your own creativity, otherwise, you're allowing their creativity to do most (some would argue all) of the work for you. And there's probably not enough of your own input here to warrant calling it a piece of art that YOU made?

So perhaps some additional thoughts about the lighting and the way in which you represent the object would make it more...YOU!

Adding some contrast would go a long way to solving this problem too - why not check out the contrast sliders in whatever program you use to edit your photos?

Wow, certainly a subject worth photographing, and makes a refreshing change from types of bird we have all seen before!

In terms of the clarity and sharpness, I feel it falls a little awkwardly between the two - I think something as delicate and detailed as this needs to either be quite blurred and dreamy-looking, or as pin-sharp across the image, rather than a mix of the two.

Compositionally, I feel uncomfortable with the slightly off-centred and half-show approach. I would personally have either had the bird's body bang in the horizontal centre or placed it according to the rule of thirds - the position chosen is neither one nor the other.
I also feel it should have been cropped at the base of the bird's body or shown the whole body (legs included) and again, not somewhere in between, for a more "comfortable" image to result. But minor gripes on a great image!! :o)

Love the colours and texture.
I'm a little distracted by trying to figure out the purpose or meaning of the title, plus aesthetically, my only criticism would be that weird little bit in the bottom left corner - I would have just made it a dark spot rather than have a different colour in it.
