I get the impression that a lot of people slag off Del's work would not have the balls to post up their own work for all to scrutinise. Might be a touch of envy that Del charges 3 figures an hour while many of these guys do £25's if they are lucky...Just the way some come across like.
It is not confined to Del btw, I also note that almost every UK based youtube spark comes in for similar treatment lol, Artisan electrics even got slammed for being able to charge hundreds where others charge pennies lol.
Unfortunately, rightly or wrongly, if your putting your stuff up for public viewing, it's going to attract critique. I think I'm some cases it's constructive and justified, in others not.
I've learnt from the "youtube sparks", both what to do and what not to do.
Ps im.not jealous of good ol'Del
Pss I don't have the balls to put my work on youtube!! (Or the time, or the inclination)
