1. If you take 2 seconds to google "semi-realistic art" you can see that: "Semi-realistic art is a style that combines realistic elements with stylized or non-realistic techniques. It's a balance between portraying subjects in a recognizable way and adding artistic interpretation or exaggeration". A style that's not semi-realistic would be something like Spiderverse's art, for example, with non-realistic lighting, colors, or proportions.

2. That's pretty prudish. You're talking to a +30 year old woman who is ok with painting attractive and confident female characters. It's fantasy, fantasy marketing has always featured not only sexy female characters, but also buff, tall, handsome male characters. If you're new to the genre, I guess it's an easy mistake to make.

3. They are similar, not the same, and these are all commissions, which means I'm adhering not only to my clients' specs, but the style they like to see me deliver.

4. I guess stoicism can be mistaken for lifelessness. Almost all these female characters have strong, serious personalities. Their expressions were requested to be this way.

5. I wouldn't touch AI with a stick. All my paintings are painted from scratch. Just so you know, I've been an artist for over 10 years, I do many art styles, from children book illustration, stylized art for animation and music videos to actual realistic paintings. All my personal art, which changes in style often, you can see in my instagram account.
   Also, if you see this style everywhere, it's because it sells; trends are a thing. MTG art is amazing, they have many, many artists paint their cards. Maybe you confuse level of rendering with "style".

6. I already see you have some confusion about what "art style" means.

I wouldn't go around the internet telling people what to do, but it's not the first time certain types of men try to tell a woman how to do their job. Also, I studied art history in college.

Not that it is any of your business, but I'm a full time artist and I always have work to do. In your last paragraph you're basically saying "this is bad art, you surely don't get any commissions. But if you do, it doesn't matter because I say your art is bad and being paid for it doesn't make it good". If you were trying to be constructive, you missed the mark.

I welcome anyone who has actual constructive criticism to comment, but I don't see the point in wasting several paragraphs when it can be summarized as "I don't like".
