Hi this is a very good macro image with good DOF. Using a tripod for images like this is always a good idea as there is less shake though you have managed to keep the camera very still. You can increase the ISO for a faster shutter speed this always helps as long as it dosent get too noisy

I am not so very knowelgable but if you mark your upload as a critique you will get professionals from this site giving you advice better than I can give you

Happy snaping

Susan
