Hmm, I don't know what you were going for regarding the bird's texture, it looks more like wood to me than anything else. The textures on the mountain are the same way. I like the clouds, but they contribute to the overall clutteredness of the composition. I don't think you were thinking of composition from the first step, so right now the background appears to be random detail put behind the alien-bird to fill the canvas rather than something that's contributing to the piece in a positive way. Having a setting rather than just a floating picture is nice, but there's no 'interaction' here, the bird feels plastered on top and disconnected from his environment.
