So I haven't been able to find enough time to do Photoshop/Gimp work, but have been playing around with this awesome app called Paper by FiftyThree. If you have an iPad, try it. I'd argue this is the best app for sketching, because the brush/strokes feels more natural than the other apps I've tried, despite it's limited color palette. So I'm posting some of my doodles on my tumblr account.
You've made me very happy with all your kind comments and appreciation for my works! Thank you! You're the best! Keep on inspiring and be inspired!
