All critique is offered with the best of intentions so you can improve and your friend will have a better "logo".
1. Brown outline is poor color choice and reduces legibility. It looks like you used an outline because you could and for no other reason because it does nothing but detract from the layout.
2. The size and color choice for the "A" overpowers the logo. The slanting of it adds nothing to what the logo should be communicating. You would be better off to reduce the height to match "Lawn Care" and then set the height of "DVANCED" to match the X height of Lawn Care.
3. Lawn Care is stretched which looks amateurish. As mentioned, the kerning is awful.
4. Lawn Care is too close to Advanced. Add a bit more line spacing.
5. Choosing a reverse for a
sign (the black background) defies the laws of legibility. It may look cool on a website but studies show that with reverses average reading speed is 33% less for white on black as compared to black on white. If your friend ever wants a magnetic
sign, the black background will absorb too much heat in the summer and the magnet can melt and/or discolor the finish on the vehicle.
6. The leaf has no relationship to the business. It would if the name was Advanced Lawn and Tree Service ... but it isn't. The only reason I can think of to explain it's presence is so you can call it a logo and not just typesetting.
The attached is my take on a starting point for your friend. One typeface family without modification, one color on a white background and a related graphic element added to make it more interesting and unique.
