It's understandable that you decided to share the package despite feeling uncertain about its quality. It's important to remember that everyone has different preferences and what may not meet your standards could still be enjoyable for others. Offering it to the community allows others to make that judgment for themselves.
If you feel that the package is not up to standard but still don't want to discard it, have you considered seeking feedback and suggestions for improvement from the community? Perhaps with some valuable input, you could enhance the package and make it more appealing to a wider audience. Alternatively, you could also seek collaborators who might be interested in refining it with you.
It's great that you have included various items such as SN columns, NN columns, and trains in the package. This diversity can make it more attractive to users who may be looking for a mix of accessories for their power lines.
Remember, sharing your work can also be a learning experience, regardless of the feedback received. It can help you grow as a creator and understand better what the community is looking for in such packages. If you are hesitant about releasing it, perhaps taking some time to gather feedback and incorporate improvements could make a significant difference.
