I like the colors and the smudging work, but im not liking yous canvas sizes man.. Try making them smaller in width, that way you don't get so much empty negative space on the far left or right, and also work with the rule of thirds
The blending is pretty well, but the background is very plain, try using stocks and c4d effects, just experiment, but the number 1 issue is your canvas sizes start working with maybe something like 400x200 or 500x300 nothing over 500x500
keep it up man.
