your "March 21st Sky" is a good example showing your technique is developing (changing the position of the camera angle from regular height to a low one) but i likes your work in general (sometimes the 'real' casual life like photos are the best rather then over digital ones) Tip: I like your plants as they are..but if you want more professional look you could try and use a white or blurred background and focus in one or a few plants at a time
My pleasure, Marilyn. I think with most thing the more you do the better you will be. A little over 3.5 years ago I never knew what digital art was and now I actually like what I create. I think the most important thing with art/photography is that if you have fun doing it the end results will show it.
