Thank you all for your comments!
PintoTess and tinyliny - I am totally with you on the faces thing. And I agree that these are slightly caricatured. For me, although I prefer to depict the dishy-faced Arabian type as opposed to the plainer type, it is also my goal to have my artwork to be as realistic as possible. And it is ever a learning process for me! The one downside is that most of my art clients are from the middle east and over there they love to see the Arabian essence 'to the extreme'. So I am often compelled to extreme the Arab type more than I would like, in order to make my clients happy.
However (and I hope I won't be I tarred and feathered for this) I do LOVE to see an Arab with a dishy extreme face! To me that, and the snort and blow, tail and fire IS an Arabian...without that, for me at least, an Arabian is 'just another horse'...
Again, thank you all for your input! Keep it coming :) I'll have updates up soon.
