not trying to be mean but I like the preview better than the image ... :/
you need to work on anatomy and form before tackling an image of this size with a person in that pose. might I suggest a WIP thread in the PJ forums so we can help you improve this?
The bg is cool but you still have to work your body !
The global result is quite nice (and your brilliant colors give a lot of energy to your pic ^.^)
(Manu : loving nerdish jokes >w<)
Nice composition, colors, overall feeling!
Light is not so consistent: if the sunrays are accurate, the guy should be strongly backlit.
And, remember using heat resistant glue - sorry, nerdish joke ;-)
I really love the sky! :)
But I think you should at least work more on his right leg - the guy seems to have two left legs. :x
