Logos need to be legible. This isn't very legible, as the "T" could be a looping "L" or is it a "T"?
The "h" could be a "t" with a loop and a "z" at the end.
At the moment it resembles some sort of needle work with a sowing pin.
You've got grunge detail at the edges of the circle, these won't reproduce well at lower sizes, or across various mediums:
Faxes, business card sizes, embroidered, smaller sizes, foil stamp, em- debossing, et al.
When going to smaller sizes, especially on a photopolymer plate, you are likely to lose detail where the emulsion will simply break apart or fill in because the gap is too thin, resulting in a poor production of your logo. Although printing machines are excellent these days, there are some printers who have not taken the leap into the 21st century with their printing equipment.
Tried to simplify the signature even more so it reads clearer and now got the logo with 'Singh Bansal' and 'Singh' and 'Graphic Designer' on it. I think using just my first name could work, having had a look at it on Business Stationary to begin with.
