I love all your avatars (and other work as well). I really like the more subdued reflection effect you used on this image on the Arch logo. I think you should use this effect more regularly (as it obscures the main image less in my opinion). Of course you’re the pro and I have trouble drawing a stick man, so I’m hardly qualified to say what is best.
Just thought I’d give you some feedback. I hope that doesn’t offend you.
Keep up the great work.
