Now, look at the reference picture of Umbreon. DON'T PANIC!!!!! He just looks scary to create because of the pattern that he has. Close your eyes, relax, and imagine Umbreon WITHOUT his patterns. Once you pictured Umbreon without his patterns, he's just a solid color type.
Okay, PLEASE DON'T HYPERVINELATE ON ME!!!!! ><; Like we did with the Umbreon picture, just close your eyes, relax, and imagine Arcanine WITHOUT his detailed pattern. Without his patterns, he's just a multi-colored type.
ANYWAY, back on topic! If you're planning on doing a Sonic the Hedgehog group cosplay or just want to do Knuckles here, then go for it! Again, use the patterns 3455 (pants view B) and 2341 (view A).
Here, Knuckles doesn't seem difficult at all! In fact, the only thing you should worry about is if the leotard and stretch pants will fit you. If they fit, then let your creative juices and cleverness fly!
Now, again, same aspect here, the only difference would be to make the front of the leotard white. Right now, the tail and the ears are not our main concern. The only concern at the moment would be the hands and feet. Study his hands and feet. It's TOTALLY different from the four-legged creatures, huh?
Again, no throw on clothes are allowed in this one either. You could if you wanted something quick and easy with no hassel, but once again, it's not going to look professional. If you're entering in a cosplay contest, people in that category are going to want professionalism in sewing skills and craftsmanship.
Like Knuckles, Raichu doesn't seem difficult at all! In fact, just make sure that the leotard and the stretch pants fits you. If they do, then let the creativity and cleverness fly!
Alrighty then, this should help you ease your mind and hopefully help you for making the Pokemon cosplays and any other creature cosplays more professional looking^^
