First wad is no excuse, but honestly, does ANYONE here make professional-grade sprites? I think not. Not even SSNTails does, really. He's good, great even, but not professional.
So, I'm not expecting you to make professional sprites, Sky Ninja, but that doesn't mean you can ignore criticism because you're "new". You can either always be "new" or build up your skills, and to build them up you have to listen to opinion and keep spriting until you run into something good.
Look where Roboegg99 ended up. Skill-less, unenthusiastic, hated and banned. (and the icon of "bad egg") If only he listened to and learnt from critisism, and made an effort to improve...
On the contrary, look at Mystic. His first maps weren't good, but now his current maps are great. He listened to criticism, learnt from his mistakes, and improved through practising.
I know you've been somewhat listening to criticisms, but let me ask this. Are you a Roboegg99 or a Mystic?
