Hi Marney! Here with the critique you requested!
your banners are really nice and floaty! the second, third and fifth ones are really good. the colouring on the first one is a bit murky, and the text is too strong and definite for the mood of it. The background of the first one is really pretty, but the girl is too over contrasted and sticks out of the banner too much. The text is again, too strong and definite.
the colouring of all of these is really nice.
The text on the third one is perfect, but on the first two it's again, too definite. the font choice is good, though.
Try to stay away from strokes, they can sometimes work, but generally they don't. if there's trouble with reading text, you can add a new blank layer and use a big, soft brush to add a white blob which you could put text on top of. Another option would be to add a box and put text on top of that.
Those icons that you have at the moment are gorgeous <3 They have simple but great colouring, beautiful cuts and they're just... gah. Gorgeous. The only advice I have for these is to make more, perhaps trying out some text on them or something.
You have a clear and definite style, you just need to improve your text and MAKE MORE STUFF! to get you to the next level.
