WARNING: Read before you react with one of them faces.
Hariet is drawn and animated very well, of which there's no need for improvement. That's positives done, onto the negatives.
Yes the focus is on boobs, yes, the nippes are partially exposed, they're in the tags, but I'm not going to touch on that. Or myself.
The submission is also way too short, which is just under 4 seconds and even then it reuses frames. I get animation of this quality takes time, but you rarely work on anything that takes more than 3 weeks. Most other animators would spend months on a single animation several times this length.
I believe you understand the 'fast, cheap, and good' formula for making projects, which also applies to making animations on Newgrounds. In this case, 'fast' literally means how fast you upload animations, and 'good' represents the amount of effort you take in order to make the animation look perfect. Since you're not collaborating that much and only ever post solo projects, 'cheap' can instead be substituted for how long the submission is, but the formula remains the same.
You can either prioritse on making something 'fast', 'cheap', or 'good', but you cannot max them all out. You are forced to sacrifice at least one aspect of your project.
It's clear that your submissions are 'fast' and 'good', but not 'cheap'. Newgrounds tends to prefer creators who prioritise 'cheap' and 'good', often spending months on a single submission. Sometimes you can make smaller 'fast' and 'good' submissions like this one, but generally you should focus on 'fast' and 'good' if you want to be respected by the NG community.
