I prefer the broader strokes and lighter background of your first attempt, but another version with a coloured background is good thinking and good practice for your first steps into the vast creative world of layers, the rooster is very colourful, and the background is too similar tonally, blue was a good choice it is a complementary colour to your overall design, a subdued blue/grey might work better, by all means flood fill, that's what it is for, but you could go to wet in wet watercolour on your background layer and give it a few seconds with a sargent brush, and even soften it to give an illusion of being out of focus and in the distance, you have another choice too, you could play with a gradient background sometime, the edges of chooky are too sharp giving the appearance of a cutout but you are still learning and learning fast and well...... a very brave and happy first attempt into a somewhat confusing world at first, and I am not being picky just suggesting, I can see what you are capable of, and have done so for some time, just keep practicing and enjoying, as you say it is not finished yet, but it is time to remember the words of Winston Churchill...... "Now this is not the end. It is not even the beginning of the end. But it is, perhaps, the end of the beginning." Some of his speeches still bring a lump to my throat, and so will your art.
children paint because they don't know they can't - so what happens as we become adults? - Me
Life is very nice, but it has no shape. The object of art is actually to give it some, and to do it by every artifice possible - truer than the truth. - Jean Anouilh 1910-87
