its best if you only resize things by incriments of 100, unless you're using Photoshop. Overall, it's not bad, a lot better than some of the stuff here, but it's best to have more than one issue before you start posting them.
yeah remove the font change it to something more readable
and the out lines of the sprite i can still see the color red
but except for those things i like it
Sorry, but I will have to say a few things
1)Use speechbubbles, all like them better
2)Change the font
3)The character is only a recolour
4)It looks like the normal cliche of: "Proffesor (insert tree here) gives me a Pokemon and I do a journey for obtaining 8 badges and becoming a champion"
5)Charmander didn´t seem bad...in fact, it seemed like on top health. Try to change their faces
