Not bad but could have been better
I know that you didn't plan a BG but I think that the BG could have used a little more thought put into it. The pose is good although I think the forward arm may be a little short and stiff. Pallet wise I like what you have chosen and there is a good silhouette. The rendering is not to bad but it feels like you used only a soft edge brush for almost the whole thing. It is better to use both hard, soft and textured. Mix it up a bit where you think it might need it, trust your gut in that area.
