Honestly, I really adore anyone who can work with acrylic! Although not as unforgiving as oil or crayon it's hard! I really like the one with ship, especially the details on bricks! I hope you success in setting a goal for yourself!
I don't have any art project for October. I am more likely to be occupied with study and work, I try to be more productive with writing.
October should be the month when artists celebrate themselves by doing Inktober, be more creative, and hone their artistic skill. Unfortunately it's not for me, I feel out of place as hell and it's haven't been one week. I never interested in doing things out of trend unless I like it, I can't churn out a decent drawing daily due to many factors, and ink also never been my favorite medium.
I feel somewhat pressured when i saw my Instagram feeds full of friends who are doing it (some kind of involuntary peer pressure), I feel like a failure and fish out of water. That is why I chose to quit Instagram for a while and ignore any work related to inktober, to give myself a space to focus on my own goals.
To anyone not doing Inktober, yeah that's totally cool too when you are focusing to yourself and your goals other than what people set for you. Please don't be discouraged
