If you follow these photo guidelines, then yes your photo is very likely good enough to use:
• Make sure the photo is taken in good lighting (outdoor daylight is best)
• Make sure the photo is not blurry
• Make sure no important elements are out of frame - we can't add them if they aren't in the cropped photo
• Ensure that the photo is high resolution so it does not come out blurry when printed on the cover/stickers
