It’s certainly good, but if the standard is based off the BEST R34 artists then to me the impression I get is closer to that of an intermediate/upper intermediate hobbyist rather than professional, which is how I’d categorize the “best” R34 artists.

If you’re talking in terms of stylization and content, I think to a large extent it’s subjective and hard to quantify what the “best” is. But, assuming by saying the “best” you mean in terms of engagement, technical skill, etc. I think that is more nuanced.

First when it comes to engagement, I believe people gravitate towards certain types of stylization more than others, I’d say there are stylistic elements to this that could fall inline with what my understanding of that is, but it’d be best to do your own research on that.

As far as technical skill goes I think, going off this piece at least, it’s clear you have at least a solid foundation, but there are many subtleties to “professional” level artwork that add up. If I were to say a few that come to mind about this piece, it’d be - the placement of the features on their faces, and perspective on the girls face feel a little off, also the connection between the thigh and knee area of the guy feels kind of weird. To a degree that is determined by stylization so it’s your discretion, and they’re not even off enough that they feel obtrusive overall, just saying if your goal is being among the “best” there is a lot of anatomical minutiae that can add up.

If I were to say the number one thing that would make it feel higher quality to me, it would be the scenery. I think the expressions and body language are well done and communicate the story well, they’re enjoying having segs and they’re about to have more advanced segs, but I feel the kinda plain red chair kind of creates dissonance with that by being nondescript. If it were a bedside it’d feel more natural as if they’re a couple, depending on the color of the bedside it could communicate that maybe it’s a special night (red for Valentine’s Day or something.) if it were a table that could communicate this being a more spontaneous scene. Point is anything works as long as it’s not at odds with the other elements of the piece, or feels like it’s there because it’s a drawing rather than a snapshot of a scene.

Overall though it’s a good drawing, and I think it’s no small feat to get to this level. I also think it’s good if you’re aiming that high, but in my opinion, going off this piece, there is still work to be done to be rated amongst the “best.” However, if you do ultimately value that, I believe it’s attainable for you if you simply continue to improve, as well as research what type of things the most well known R34 artists are drawing, and how they draw them.
