Hm, Tony Fleecs? He did the art on the Rainbow Dash and Fluttershy issues of the micro-series. I am not very fond of his work, to tell you the truth. His proportions, strokes, framing and motion are... all over the place. A bit amateurish, actually.
My current ranking of MLP comic artists is:
1) Andy Price (MLP:FiM #1-4, #9-12, MLP:MS #3, MLP:A 2013) - Not really faithful to the show, but really professional and full of personality and attention to detail. Awesome expression work and visual humor. Panel work must be seen to be believed.
2) Ben Bates (MLP:MS #5, #7) - Simple but very effortless, dynamic stroke. Turned from good to awesome when he dropped the conventional inks and shading he used in #5, and went to what appears to be a more personal style in #7.
3) Amy Mebberson (MLP:FiM #5-8, MLP:MS #8) - The artist who most closely resembles what I imagine a straight translation of the cartoon to comic form to be. Good designs with excellent consistency and great expression work, but nothing that really screams "awesome".
4) Brenda Hickey (MLP:MS #6) - Bold strokes and good expression work. Plays a little too much by the standard comic book rules, in my opinion. Could rise in the ranks, but I would have to see her takes on other characters before making my mind.
5) Agnes Garbowska (MLP:MS #9) - With just one issue and only three main characters drawn, there is not much to go by, but I do like the watercolor-like colors used in her art.
6) Tony Fleecs (MLP:MS #2, #4, MLP:A 2013) - Bad consistency and more misses than hits on expression work. His poses are just awkward, lacking dynamism. Tries too hard to follow the show designs, and fails.
7) Thomas Zahler (MLP:MS #1) - Just awful anatomy and almost no shading at all. Worse than most fan-artists in dA.
