Test Grey Knight Finished

So I finally finished my Grey Knight test model, I painted up the Brother Captain Stern (9/10 times will be a justicar) in my now defunct Mordrak Themed Ghost knight scheme. I think he came out “OK”… to be honest the speed painting project on the army has been fun and a learning curve but ultimately I am not happy with the paint scheme. Im in two minds: Power on, Power through and finish the army to an ok standard or strip the whole lot, rebase (32mm bases for Marines now I hear?!) and paint the army up in a different scheme doing my absolute best job? Problem is that these are probably my favourite GW marine scultpts of all time and as such I want to do them justice! Other part of me thinks that just get it painted to play with (for all ill play 40k being a fantasy player in the main) and repaint years down the line if I feel so inclined!

Anyway let me know what you think guys and what you think I should do!
