Good first attempt Chris. Would be interesting and useful if you put a bit of extra info up e.g. exposure time etc. This one looks pretty long if the clouds and the blurred grass is anything to go by.
I like the sky and skyline, can't decide on the grass blur cos it un-defines bits such as the the landing net (that is the landing net isn't it bottom left). Obviously with an ir filter either exposure time, aperture or ISO have to be sacrificed. Don't forget ir (like this) will always be mono so a bit of high iso colour noise may go unnoticed or at least can be processed out).
Sorry to have rambled on. Hope it's of help. Anyway good start, practice makes perfect.
