I actually find your Blanka quite alright, I like how you didn’t rely on charging at all and kept yourself moving… which to me is one of Blanka’s strong points…
here’s a few points you might wanna consider…
jump in MK, cl.MP, s.LP xx electricity isn’t a good combo to use especially against skinnier characters… it’s very range dependent and most likely wouldn’t land… if you end it with EX electricity it makes the combo much more reliable… but I see that you were doing this in the end… imo… if you don’t wanna use ex… either take out the cl.MP and keep it simple/scrubby or you can do ball combos… or you can simply cancel electricity from something like cr.MK
In general I feel like the places you put yourself doing random slides is very high risk and low rewards… if you watch the video again… outside of going under chun li’s fireball… you’re more or less punished every time… some characters and players can punish you really really hard for it… imo… i wouldn’t usually do ‘random slides’ unless i know it’s gonna hit at the very very tip where you’re generally safe… (and might even get frame advantage in some scenarios)
Everything else I feel like is pretty decent, I could nit pick more like certain wake up options etc but i think it’s unnecessary.
so keep it up
