If you are serious about improving your (digital) art skills then I would recommend following the online art course "How To Become A Better Artist" by "Robert Chang".
This course will change your 'artistic' life ... guaranteed. It did for me ...
Not only will you sign up for a 6 week online course full of detailed knowledge & advice but you will also get a 'life time' mentor as Rob states he will guide you whenever you are in need of artistic advice.
