I would like to draw your attention to the works 
The pictures look very unusual and “unique” as if possessing almost supernatural ability to capture every detail.
My opinion as a professional artist is that the works he is passing as real paintings are actually digitally derived from photos with the use of progressive filters and layers. Some are very basic watercolor conversions that you can get with a lot of apps these days, such as Prisma, some are more complicated with step by step procedure.
If you study the "pencil" work presented in his posts, you will find few types of very distinct patterns of strokes repeating across the works, varying only in rotation and size, suggesting that they are in fact generated by a computer.
Take notice that all the pictures seem very flat as it is very difficult to mimic thickness of paint in software. The appearance of canvas texture is easily achieved, though.
There are programs that allow you to paint over areas of an image and convert that to an appearance of a variety of mediums from watercolors to pastel chalks with a number of modifiers to control the result.
One of the most advanced programs capable of a lot of this is the Corel Painter, which he happens to mention using in some of his posts on digital art. Below is a demonstration of the Painters auto paint feature:
Another example of such program is the Dynamic Auto Painter:
There are many more videos on YouTube and there is a free trial of the Corel Painter available if you wish to play around with it yourself. It even has the divine proportion tool with that spiral you can throw on layer as in this post: https://steemit.com/art/@coldmonkey/original-art-learning-to-paint-from-inside-your-head-painting-from-imagination-a-steemit-special
The results can be very convincing if you are not paying close attention. With limited time we have to spare to look at pictures properly, it is easy to ignore the subtle hints.
This is not a pleasant thing to write but I can’t keep watching these posts get rewarded over false pretenses and say nothing. So this is my opinion, it is up to everyone else to decide what gets rewarded. The rewards are low at the moment so it may be easy to overlook this, but I hope everyone can now see these works for what they are and be mindful in the future.
