Dude. Do you REALLY have to be this rude to him? He may be inexperienced in card-making, but unless you decide to start making cards and become active in it on Card Creation Game, don't be that harsh about your judgements, and even then be respectful towards fellow card-makers.
A short, RESPECTFUL response should be given to card makers about their cards in my honest opinion.
ex- "Sonya, cool images broski, but I think that you oughta tone down the effect a little." or "Nice cards, but I think -card- is a bit OP. -small but thorough explanation why so you get your point across in a respectful manner-"
While I agree he could have done better, I seriously think you oughta take a chill pill before posting rude comments like that. You are more likely than not going to be talked to by admins/mods.
