I think your stuff looks great, especially for someone only a couple years out of school!
Three months is not a very long time to job hunt. Think of it both ways too. Would you really want to work at a place that just threw everyone an offer? It takes time, especially to find the right place. I’ve often looked for 12-18 months.
As for your portfolio, I would suggest to touch up the renders of your Bark project. The models you built photographed great, but the renders are a bit flat. Also, your graphic design skill is really high, but don’t let it overwhelm your product work. When I hire, I don’t read through every project. Therefore, you have to make the innovation obvious in the images. Also, don’t assume that I’ll flip through 5 pages before getting to your design. I like it when the portfolio starts with an image of the person’s best work and then walks me through some of the research, sketching, modeling.
