You're good with your photo manipulation skills you just seem to lack a good sense of composition and I hate to really rag on that about your pieces but it seems to be prominently the problem. If I could suggest reading the book Drawing Scenery: Landscapes and Seascapes by Jack Hamm. Now you don't need to learn how to draw but the first half of the book is pretty much entirely basic composition and how to really understand it. it helped me quite a bit and I think you'd benefit from it a lot as well. Now what I find is that the light of the rim of the planet or moon in the background combined with the contrast of her dark hair creates a focal point dead center in the middle. Which isn't too appealing in a broad sense. It can be good and in this case it's not too bad since the wings still lead the eye out from there. Generally it isn't too good though. The brightness of the piece is very refreshing to the contrast of dark blue in the bottom area, however, I find that the clouds up top might be a bit too overbearing. Maybe tone them down just the slightest bit. Good job yo keep it up I like your photos a lot.
