8/10 Mega Gallade
The new hair bother me a lot, but the outfit is fine, maybe if they used the same green tone of the Ralts line on his jacket or pants it would have been better but won't complain about it. Only the hair.
Mega Gallade seems working fine as a mega counterpart to Gardevoir, both develop more elaborate "pokeclothes" and an elegant look, pehaps the colors choice is what that does the trick on its look, if Gallade kept the green pattern on its chest and arms I'd say they were the same looking Pokemon, even more close than Gardevoir is to Mega Gardevoir. Solid Mega however I was expecting its waist to not be circular and flat anymore.
>>209138364/10 Mega Sharpedo
This pretty much what overdesigned means.
The presence of too many yellow stripes doesn't help it, remind more of the primal Kyogre, but doesn't work fine on Sharpedo's shape. The saw spikes are good but overall don't go well with the stripes on its nose. The chin is basically like Garchomp's one with a splash of redundant color to evidence it.
>>209140016/10 Mega Camperupt
Camperupt already has a goofy look, the hair cape it got resembles both Stoutland and Slugma while the head hair and the defined "shell coat" remind of Shellos line. Forced "M" mark as well when it could have been more hidden and harmonic like the few things Mega Sharpedo had on it if not the only one. Quite confusing design. Especially when used on a generally forgettable Pokemon.
