Hi Villanova, thnak u for your support! I dont know how to tell you exactly what kind of style it is, im not really good artist but when im doing my stuff I only think is to be diffrent to others. Practice practice and more practice so you can established your own style.
I only use Photoshp and some cool free brushes. But my style also inspired with other comic artists.
Submit more designs and look for other works but dont copy it just use them as an inspiration. You need to follow your feelings, if you tried to cpy somebodys work you cannot work freely. Composition,color and style is your best tools. I hope it helps. Peace!
