>>34658101A. Sleek option for a Speed and Physical Grass/Fighting type in the same venue as Blaziken. I like its color scheme but magenta doesn't fit with a warm green color palette, I would change it for an orange or red color. 8/10.
B. We already have a bulky brawler Grass type starter in the form of Chesnaught. It wouldn't add value to the Pokemon roster. 4/10.
C. No strong opinions for this. A neutral and very balanced design if the designers bet for "play it safe" in designs for starters. It's well designed and would pass nicely as an official Pokemon for 5th or 6th Generation. 6/10.
D. Too complicated in my opinion and it would represent repeating Decidueye's mistake again in designing a too dark and complex grass starter. 3/10
E. Similar opinion as A, but it would fit more on a Grass/Psychic type, which is lacking in the current Pokemon roster. Would bet for more vivid colors though. That scheme looks too dull. 9/10
F. Lucario expy and probably a good candidate for "teenager's favorite Anime Pokemon" as did Lucario, Greninja and Lycanroc. The carrot is out of place and would replace it for something more weaponlike like a tree branch. 7/10
