A bit plain IMO sorry,you should have something a bit more eye catching.
Its yellow what more is gonna catch your eye 
some of you may be able to remember when i changed over to wfp 3 yrs ago i had a very very bright yellow rascal van
i got noticed and remebered every where i went picked up lots of work and a couple of big commercial contracts
i even had one guy driving after me asking me to do his windows i do believe you need something that stands out but writing doesnt always do it
