Glaceon can use any attack that Eevee knows with the addition of Ice-type attacks. As a fully evolved Pokémon, Glaceon can learn Hyper Beam and Giga Impact. In addition to that, it can also freeze its fur to make it stand up like needles - similar to its evolutionary kin, Jolteon. By controlling its body heat, it can also freeze the atmosphere around it to make a diamond-dust flurry.
The simplistic style you use is very eye catching and although simplistic, has immense detail. The sharp points and seamless curves only add to the outstanding look, by pronouncing features of of Glaceon that were overlooked in the anime or games. The incredibly detailed shading give it a feel of depth and helps towards, again, pronouncing features of Glaceon that have not been seen in this way before.
Overall i think this is incredibly well done, and has a very unique style of simplistic, but highly detailed.
