You can also hard-refresh or clear your cache to make the new image show up. PJ doesn't mark the changed image as changed for some reason :/
The glasses are much more visible now! However, them being blue looks rather strange to me, since it reads as if the glasses are actually blue, rather than as "cartoon glass is blue". Glasses have transparent glass, and I think you can communicate that easily enough by making just the frames visible, and maybe adding a bit of shadow on the above the eyes from the lens edges. Here's an edit where I tried to do that.
By the way, if you don't add any shadows to the bottoms of the feet, the character will look more like they're planted on the floor. If there are visible shadows, it looks like the character is floating slightly above the floor, or has ball-shaped shoes.
OK, I added glasses to the guys. Both of them, tough there seems to be some caching issue as pixeljoint shows the old sprite for the walking scientist until you download the original gif.
I see... Thank you very much eishiya! I'll try and make it look better. :)
The eyes/glasses look very blurry and it's not immediately clear that there are glasses. I think it would be good to stylise/emphasize the glasses more, even if it means making the eyes behind them less visible or adding unrealistic shadows and colours to them.
That looks awesome! :) Tried applying the same to the walking scientist https://i.imgur.com/jhmAUWj.gif . If it's OK I'd like to substitute the images with your improvements, and add the aprorpiate descriptions.
