The beer in the next town tastes better 
Great line work. I like how the thickness takes into consideration the nearness of the object or a cast shadow.
For almost a month I forced myself to draw and failed. In the first pic, it seemed to me that the line, as it is, is not enough and added a few details. Then I started coloring this part, because after adding the details, I decided to just try to find the style I needed. And the colored result didnāt satisfy me, itās still too cartoony, flat and simple. In the second pic, I tried to be a little more realistic, but in the end it still turned out flat and simple 
In the third pic, I had already come to terms with this bad line and lack of detail and colored it only to realize that I was going the wrong way - this is not what I wanted. And again I donāt finish the page because Iām starting to procrastinate more and more. 
It demotivates me. So Iād better leave it as it is and start something new.
why canāt I change the thumbnail image? I know that I need membership status for this, but how can I get it?
Can you edit the title of your topic with the pencil icon at the end of the title?
If so, do you see the āselect thumbnailā button.
Your account is at level 1: basic user. It may be that you need to be at level 2: member or higher. If so then keep on visiting and keep on reading topics and making reply comments and posting your own work to get to level 2.
If you tell me the link for the reply that contains the image you want as a thumbnail then Iāll be able to do that for you when Iām around as will any member of the forum.
I don`t have that pencil icon 
@Archy_Bot: Then you need to participate more, be more often around, reply to topics you find worth answering, things like this.
And maybe, but Iām not 100% sure, you should take Kikiās ābeginnerās courseā, that will be offered to you in the second or third reply from Kiki, if you follow Kikiās replies in the āGreetings!ā message you got directly after registering in the forum.
This is not mindless bot chatter, not blah blah blah, it is addressed to those who are seriously interested in this forum.
My impression is that those who donāt take the course will take longer to obtain these rights. The mentioned 
are the rights obtained earlier, I can only guess, unfortunately I did not need to post videos or links in my first weeks here, so this is only guessed on the experiences those who took the course made.
In case you have bookmarked that message, as Kiki advised you to do, you can return to it and play that question and answer game and absolve the tasks Kiki has for you.
I believe, but can not guarantee, this helps, because those users who followed Kiki through that course were able to post videos in their first posting in the forum. All those complaining āthey can not post videos, or links, in the beginning on the forumā, have not absolved it - that is an observation I made.

Iād count that as a win.
