I love your work! Did you just start altering MTG? They look pretty good. A few things you should know if you intend to start doing it more often.
1. The card name, mana cost, and spell type must remain visible. Also, some judges will not allow alters that drastically change the graphic (apparently because people who dont read english are unable to distinguish the card without asking)
2. To be tournament legal the thickness of the card cannot be obviously different from an unaltered card. I recommend using Golden fluid acrylics. They are a tad expensive but the effect is WELL worth it. Only my mana leak and lingering souls used that paint so far (been super busy), but they are worth every penny!
Please keep up the good work!
