Maybe it's me, but «Blue size 24» appears the same as if you where only using capital letter, seems more like shouting than a calm message.
As for your sprite, I think adding more fire on the pokemon would give it a better fire looking. Currently he seems more doing a fire puch than being a fire pokemon, well IMO. Ponyta,Rapidash, Marcago, Infernape, Magmar are example of pokemon you could use is you want to add more «fire type» to your pokemon. There is no need to add much, but I think a bit would help seeing a good retype more than a recolor Lucario.
