I have never painted much sky or landscape but I have a couple of commissions coming up that require it.
This is me getting my eye in for clouds.
First attempt (with no reference and minimal googling)
Result: far too bold and splotchy for what I want. Looks like rhubarb custard.
Second attempt (a short Google later)
Result: definitely better
Third attempt (with the guidance from my new favourite artist, Roland Lee)
Result: looking good
Fourth Attempt (still rolling with three Roland style, but no reference)
Result: bled a little but definitely getting there.
