Welcome to Librarium Online!
Nice and bright colors but for the love of god and all that is holy weather that beast down. If you never used the GW washes Id suggest playing with them. Or stippling some rust on it. But keep up the good work.
I dont do weathered, orks are garish and bright and insane, RT is when I started painting and I will carry on making people vomit with my insanely bright, undamaged models but yeah more seriously, thanks for the critique but I do like my orks to be shining across the battlefield, maybe blind my opponent into losing
In that case I commend for for burning my eyes out. If you are going for really bright then I would suggest doing an even brighter edge highlight. I see that you have one, but for the red try mixing some bright red and yellow or orange. That will give you an even more distinct edge and look. I do it with my killkanz, ... after I weather the crap out of them
