the trick is in finding your own calm place. no guru can take you there, because in your own mind you are god. until you realise this the distractions will keep stopping you from getting where you want to be. they can never be inside your own head because you are in control in there. its tough, and very annoying to try and get to, but well worth the effort have a wonderful day my friend!!
You definitely should this turned out great! Even though I personally feel the B/W style has a really bold impact, and can fend for itself without depending on colour lol, it's always good to brighten things up, and if it challenges you, forces you into you uncovering new techniques or processes then thats what it's all about.
I've just always found it daunting, I'm not great at combining colours that actually work, because I have had little experience doing it, because of that I never choose to do it, vicious cycle!
This worked really well though man, and I think it's just discovering that part of the process in colour that you also found with pen, then it'll no longer be tedious! Not sure if that makes sense, but there ya go haha.
