Why hello there and welcome to the Pokemon Community, Gef! I think your introduction is pretty fine, I mean you were able to manage to tell some things about yourself and just give the most important information about the things that brought you over here in PC, so great job! It's nice to see another pixel artist around, I'm sure the ones who are in need of spriters at the moment in the Emulation board would love to have you on their team! :D
Megan already introduced you to the Pixel Art section, I'll be definitely looking forward to see some of you works there but of course, first of all you need to have 15 posts first before you can post images. You can roam around the whole forum besides the Pixel Art and Emulation boards, there are lots of interesting discussions around ant it's really easy to participate in 'em as long as you have game play experience in the games, but don't worry PC also offers topics that aren't related to Pokemon, so you'll just fit in just fine here! *^___^*
Your English is perfectly alright, no need to worry about it as long as we can understand what you mean then it's all settled. I am not a good English speaker myself too and it isn't my first language, what actually helped me improve my grammar were the forums I've been to, I just keep on interacting with others and it definitely helped me improve a lot! Hopefully, forums will do the same for you as well!
With that, if you have any questions, just send me, or Megan a message, we're here to help you out! In case you still haven't given the rules a read, I suggest reading it now, you don't want to get into any trouble don't you?
Have lots of fun and see you! :3
