First of all, thanks for your positive feedback!
And no.. there is no reason for the large canevas, actually there was the title placed, but i have to remove it, cuz every pixel in a picture have to be placed be hand so..
Is there a reson why the canevas is so large? Just curious 
. It's nice a first try though. Keep at it!
Great early effort.
here you have a lot of banding which is considered very ugly in pixelart.
Make sure you view and read cure's pixelart thread and the noobtorial thread in the forum's resource section for tips and general info.
Thank you! Ok I definitely take a look at it, thanks for your great advice!
