Where have I cut

[Maxbashing]

Ok so i am thinking about having my second go with liquid mask as I have been inspired by the recent work that has appeared on here.

1 thing i struggled with last time was being able to tell where I had cut the liquid mask and wondered if there were any tricks of the trade. I found that if I angled the balde slightly I could see the cut line a bit better but this wasn't always possible in the fiddly bit.

Anyone got any thoughts??
