I usually use Talens masking fluid and at this moment(since I forgot to pack it with me when I was moving out!!) I'm using HORRIBLE masking fluid! It sticks on the paper like glue, ugh! Need to buy new one quickly, so maybe I'll try Winsor-Newton too :3
Yeah, haha, those eyes turned out to be HUGE! 8D Still trying to decide what to draw and paint more, I'm kinda for mood doing "portraits" of my characters. But then again, I really should be doing more anatomy practises and that stuff. I need a live model!
