I have to kind of disagree here. Not that what you're saying is wrong, but that I think Wom1998 is looking for advice on the general direction of the piece, rather than the polish and rendering part of it.
I can see why you're looking for direction, cause I am kind of lost myself when looking at this. The wings show that the character is angelic, yet he wears quite regular clothing, or perhaps a bit more gothic from the middle ages variation from that. The background doesn't give me that much either, it doesn't tell me where he is or what he is doing.
As the piece stands, it's not saying very much. What is your original vision for it? For example, do you intend this to be a sort of angel that is coming down from heaven? If so, perhaps adding a sky-looking background would help. Or is he landing close to a town or just the ground? The pose isn't very effective at telling us what is going on either. I think you'll have to think a bit about what is actually going on in here before getting back into it. So, maybe this is an angelic warrior that has just landed at hells gate. In which case, you can have a more aggressive pose that shows the angels fierce expression, with wings arcing to dampen as much of the fall as possible. The character could hold a sword or something that would help it fight, and the background could be that of hells gate or something alike.
Either way, this was just an example, and I am not advising you to actually do this. But, that you think of a scenario or story, that will make it far easier on you when making it!
