I love #2 and #4, the angles are great. They are a bit unusual and therefore interesting. Nice work, but HoosierJoe is right, they seem to lack a little contrast, but that can be easily fixed. Great job for your first attempts!
Thanks for the feedback. I will try to adjust the contrast and see if I can touch them up a bit. I am still pretty new with photoshop so any input is greatly appreciated.
The first is a tad noisy, yes, but that smile! It melts your heart! With a model like that, with SUCH as cute, slightly mischievous, smile, you just cannot go wrong. I really like that first photo very much because of that smile! Just some more contrasts, and a bit of USM, and ... cuuuute!
