Logo feedback please!

Another solution would be to add blocs of flat color instead of add weight to the lines. You can then keep your thin lines as a motif (giving some texture feeling). What I would do (and what I actually do) is, now that you have your "illustration" set as a sketch, confront it with some typo (your name, and slogan, if you have one). Get them next to each other (or above or below, try it), and it will make more sense, because you can then have a feeling of the contrast (here you have only the lineart, and away from everything else, it works, because you have a unity of the space and the contrast, black and white only).

With your text next to it, it will take another dimension (thin or thick typo, round or square, fantasy or serif, etc...).

Next you would maybe try to mix it with your name, and it will give you another feeling (don't hesitate to change every bit of it). Your illustration is a good concept, keep it, but what is important (in my opinion) is the experience of your logo in its whole, more than the details, the quality or the complexity of a good illustration.

I love how detailed the hair is! Now depending on your brand and website. You might want to consider spacing. Most logos are recommended to take an invisible shape for better spacing. Yours could cover a "square" or "circle" but due to the complexity of the illustration, you might want to simplify to rigid shapes.

You might also want to consider line consistency, in smaller (mobile) screens, the super thin lines may not show up and make the design look unfinished.

I love the personality of the design and I hope to see it in action soon!

I agree with the feedback Maria provided. I'd get rid of those real thin lines by increasing the line-weight. I feel that the logo fits well into a 'square' or 'circle'.

Thanks guys, I appreciate the feedback. I will definitely work on those thin lines. I also think I will fit the design into a circle.

We'll be waiting then :).
