Branching into oils and acrylics

I am a bit lost these days as I am teaching myself - through some online webinars, to use oils and acrylics. 

I've already did two acrylics on my own and working on a third one of my own accord, but I decided to take some webinars to learn faster the ropes of the trade! 

Acrylics are pretty easy, but I have to tackle how to extend their wetness and the oils are great, but I've used a small flask of terpenoid in one go! So, I will be doing a bit more of this before going back to do my own artwork that I will sell.

Here you can see my results so far. The seascape is made in oils and the rhododendrons in acrylics.

Would love to hear your thoughts- just contact me on the comment page and let me know whatever you think! :) Martina
